Is It Normal To Feel This Angry?

As I said In my las blog I god rejected by a girl that I really like.
SAD FACE.
It get's worse, unfortunately.
I went to see Russel Howard last night with some mates (amazing) and i noticed that my m8 who went out with this girl was texting someone.
I just kinda let it go even though they had been flirting infront of my face. (He didnt know that I had asked her out.)
I was crashing @ his and we started talking. He was like "when was your last girlfriend?"
I couldnt really remember becos it was like 2 years ago.
Sad Face
But he was like. well maybe you should at least try. So I told him I had asked out his ex Girlfriend. He was a bit pissed off that I hadnt asked him before hand.
Understanderble.
What happened next really pissed me off tho. At first he was fine like, well you'll get over her "she's a bit weird anyway."
Fine
Then we kinda thought of a list of reobound girls and he offered to help me because he knows how crap I am with girls.
Even Better
This is what made me pissed off, not so much with him but with her.
We changed the conversation and I asked him who he had been texting during the gig.
He went all awkward and I had already guessed.
Feeling Pretty Shitty here
He showed me the texts and I was right.
Im not saying I own either of them thats just retarded but...
WTF!
She was mocking me menatally and thing was. She text me all nice asking me how the gig was not 5 mins later.
Feeling Very Shitty.
I didnt answer, she was like. "your still annoyed about me saying no to you?"
Still No answer from me
I decided im very annoyed.
VERY
I went home and listened to Platypus
ALOT
My m8 was rele nice about it tho. he was like "im rele sorry, i didnt know how you felt."
YEAH BUT SHE DID
Thats why I am very angry.
